Why do you need to validate originating numbers? 

Both fraud and origin based surcharges are on the rise around the globe and pose a threat to the revenues and margins of the telecoms industry.

By pre-validating A-Numbers, carriers avoid having to block traffic due to uncertainty of origin and can also grow customer confidence with their trusted traffic status.

New regulations

One of the first regions to mandate A-Number validation and checking against a Do Not Originate (DNO) list was the USA. In trying to prevent internationally generated robocalls that appear to come from a domestic range the FCC mandated that providers not only authenticate calls using STIR/SHAKEN but also check all calls against a DNO list and block any that appear on it. They must also be able to trace calls.

The USA is not the only territory to introduce these legislations - the UK introduced a similar requirement to validate against a DNO list in November 2022, Ireland also has a DNO list and others around the world are currently in consultation.
